Feature Request: Select portfolio PCs for Encounter / Tactical console

[KungFuCharlie]

I have a large group of players in a single campaign. Sometimes they all show up, other times one or more is missing, and sometimes I run a mini-session for a limited number of the players. Currently I have to export the characters present into a new portfolio and then import them back into the campaign portfolio when the session is over. It would be a lot easier if I could just select the characters that I want to appear in the tactical console for any given instance.

Or is there an easier way to do this that I am completely failing at using?
